Installation/Operating Instructions
220V Envoy Electric Projection Screen by Draper
Copyright © 2013 Draper Inc. Form Envoy220v_Inst13 Printed in U.S.A.
Operation
When screen is first operated, be cautious! If automatic trap door does not
drop open immediately when switch is flipped “down”, return switch to “off”
and free trap door and/or recheck electrical connections before proceeding.
Cycle unit down and up several times to confirm satisfactory operation.
220V Single Station Control—3-position up-off-down switch permits opera-
tion to be stopped at any point. Factory adjusted limit switches automatically
stop screen when fully down or fully up.
220V Multiple Station Control (Not CE approved)—Switches are similar
in appearance to 220V Single Station Control. Screen stops when switch
is released and may be restarted in either direction. Factory adjusted limit
switches stop screen automatically when fully down or fully up.
24V Control—Three-button up-stop-down switches stop at any point desired,
operate in any sequence. Factory adjusted limit switches automatically stop
screen when fully down or fully up. Installer should incorporate an all-pole
disconnect in the fixed wiring.
Key Operated Switching (Not CE approved)—Two kinds of key-operated
switches are optionally available with this unit. 1 The key-operated power
supply switch controls power to the screen and switches. When it is “off”,
the switches will not operate screen. Key may be removed from the switch in
either “on” or “off” position. 2 A three-position key switch permits the screen
to be operated directly by key. In this case, the screen’s operator must always
have a key.
RS232/Ethernet—Serial communication and network communication
optionally available with wall switches, RF or IR remote.
Adjustments
Please Note: Screen limits are factory set for optimum performance of
the screen. A procedure is outlined below for minor tweaks, but any
adjustment of these limits may negatively affect the flatness of the
screen surface and could also void the warranty. Please check with
Draper prior to resetting screen limits.
CAUTION: Always be prepared to shut screen off manually when new
adjustment is being tested. Screen may be severely damaged if viewing
surface is allowed to run too far up or too far down.
CAUTION: Be sure all switches are in “off” position before adjusting
limit switches.
Adjusting “fully up” position — “Up” limit switch, located immediately
above left end of automatic trap door, is tripped as door closes. If door does
not close fully, limit switch should be raised slightly. If door closes too tightly,
switch should be lowered slightly.
Remove steel plate attached to threaded neck of “up” limit switch by removing
hex nut securing it. Removing plate exposes three Phillips head machine
screws which hold limit switch bracket in place. Turning these screws clock-
wise will raise limit switch; turning them counterclockwise will lower it.
Raise switch only in quarter-turn increments. When operating properly auto-
matic trap door should close gently and rest against but not press on rubber
bumpers above it. Adjusting automatic door so that it closes too tightly will
damage screen.
Adjusting “fully down” position — “Down” stopping position may be ad-
justed by turning the white limit switch adjustment socket. The white socket is
located on the left end of screen roller and is accessible to a screwdriver/Allen
wrench (4mm or
5/32
") when automatic trap door is open. Access is easier
when bottom board is also open. (Do not adjust the yellow socket which is
next to and in back of the white socket). Turning the white socket counter-
clockwise will allow the viewing surface to run farther down. Turning it clock-
wise will shorten the viewing surface, causing it to stop in a less extended
position. At no time should viewing surface be unrolled enough to expose any
part of screen roller.

If you encounter any difficulties installing or servicing your Envoy screen, call your
dealer or Draper, Inc. Spiceland, Indiana, USA, 765/987-7999 or fax [phone].
Caution
1 Read instructions through completely before proceeding.
2 Follow instructions carefully. Installation contrary to instructions invali-
dates warranty.
3 Do not lift case in center. Lift the ends simultaneously to avoid damage
to case and surface.
4 Entire bottom of screen case should be unobstructed to permit proper
operation of automatic trap door, and access to bottom panel for making
electrical connections or servicing.
5 Screen should be installed level (using a carpenter’s level).
6 Nothing should be fastened to screen dowel, viewing surface or
automatic trap door.
7 Operating switch(es) packed separately in screen carton. Do not discard
with packing material.
8 Screen operates on 220V AC, 50 Hz., 1 ph. current.

Hanging Screen
General:
When locating viewing surface and checking clearance for screen’s opera-
tion, remember surface is centered in case. Screen is normally recessed
above ceiling and may be installed in a variety of ways. See typical installation
detailed on back of this sheet. Regardless of mounting method used, the fol-
lowing points apply:
1 Screen should be lifted into position only by the mounting brackets.
Keep case level by lifting both ends simultaneously to prevent
surface damage. Never attempt to lift screen along its length.
2 Screen should be positively and securely supported so that vibration or
even abusive pulling on viewing surface will not weaken installation.
3 Installer must insure that fasteners used are of adequate strength and
suitable for the mounting surface chosen.
4 Entire bottom of case must be readily accessible after installation is
complete.
5 Hinge on bottom board and particularly hinge on automatic trap door of
screen must be permitted to operate freely. Front and back of case must
be straight—not forced to warp or bow. Hinges must be free from mastic
or paint buildup, and doors must be unobstructed by ceiling tiles.
6 Do not use screen case to support adjacent sections of ceiling.
7 If trim pieces must be attached to case, do not permit screws to protrude
through 19 mm (¾") wall of case. Do not attach trim with nails.
8 If case is painted, slots around doors should be shielded to protect
viewing surface from paint splatters or overspray.
9 Do not seal unit in ceiling until electrical connections have been made
and screen has been operated successfully.
Electrical Connections
Screen operates on 220V AC, 50 Hz., 1 ph. current.
Junction box is located just above bottom board near left end of screen.
Bottom board is held closed with flathead screws and may be opened with a
Phillips screwdriver/Allen wrench (4mm or
5
/ 32 "). Automatic trap door is held
shut by viewing surface and must not be forced open. Junction box contains
brown, black and blue pigtail leads and green internal ground wire, per wiring
diagram on reverse.
NOTE: Screen has been thoroughly inspected and tested at factory and
found to be operating properly prior to shipment.
Screen is shipped with internal wiring complete and control switch(es) fully
boxed. Wire connecting screen to switch(es) and switch(es) to power supply
should be furnished by installer. Connections should be made in accordance
with attached wiring diagram, and wiring should comply with National and
local electrical codes.
All operating switches should be “off” before power is connected.
These instructions are meant as a guide only. They do not imply any responsibility
on the part of the manufacturer for improper installation or faulty workmanship at
the jobsite.

Limit Adjustments (Built-in Low Voltage Motors)
Please Note: Screen limits are factory set for optimum performance
of the screen. A procedure is outlined below for minor tweaks, but
any adjustment of these limits may negatively affect the flatness of
the screen surface and could also void the warranty. Please check
with Draper prior to resetting screen limits.
CAUTION: Always be prepared to shut screen off manually when
new adjustment is being tested. Screen may be severely damaged if
viewing surface is allowed to run too far up or too far down.
1Connect the ILT switch to the motor via the terminal blocks, or via the
modular port using four conductor modular cable. When using modu-
lar cable, the cable connectors MUST NOT be crimped in reverse, as
with standard telephone cable. (For a Dry Contacts Wiring diagram,
see page 3.)
2Set the slide switch to the lower position. Press and hold the DOWN
button on the switch to move the viewing surface to the desired lower
limit. If the screen moves in the opposite direction, release the DOWN
button and press and hold down the STOP button for four seconds.
This will reverse the operation of the UP and DOWN switches.
3Move slider switch into center position. Wait a couple of seconds.
Please Note: If you move the slider switch from down to up in one
motion it sets the two limits in the same position.
4Set the slide switch to the higher position. Move the viewing surface to
the desired upper limit by pressing and holding the UP button on the
wall switch.
5Return the slide switch to the center position to return to normal
operation.
6To set the viewing surface to an alternate format position, move the
viewing surface to the desired position and press the STOP button.
Press and hold STOP button for at least 3 seconds to record position.
Please Note: Pressing and releasing the UP button on the switch will
move the screen to its upper limit. Pressing and releasing the DOWN
button will move the screen to its lower limit.
While the motor is in motion, pressing the STOP button for less than
two seconds will stop the viewing surface at its present position.
Once the motor is stopped, pressing the STOP button will move the
viewing surface to its alternate format position.
Pressing and holding the STOP button, when the motor is at rest or
in motion, for at least three seconds will record a new alternate format
position.
